Ingredients
Scale
- Gluten-Free Flour Blend:
- 1 ¾ cups (approx. 245g) High-Quality Gluten-Free All-Purpose Flour Blend (Must contain Xanthan Gum) – Choose a blend designed for 1-to-1 replacement in baking (e.g., Bob’s Red Mill 1-to-1 Baking Flour, King Arthur Measure for Measure). The presence of xanthan gum is crucial for binding and texture in gluten-free baking.
- Chocolate Components:
- ½ cup (approx. 45g) Unsweetened Cocoa Powder (Dutch-process recommended for deeper flavor, but natural works) – Sift if lumpy.
- 1 cup (approx. 170g) Chocolate Chips (Semi-sweet, dark, or milk) – Divided. Choose dairy-free chips if needed. Mini chips disperse nicely.
- Zucchini:
- 1 ½ cups (approx. 180-200g) Finely Shredded Zucchini (about 1 medium zucchini) – Do not peel. Crucially, squeeze out excess moisture after shredding.
- Sweeteners:
- ¾ cup (150g) Granulated Sugar OR Light Brown Sugar (packed) – Brown sugar adds extra moisture and a slight molasses note. Coconut sugar can also be substituted 1:1.
- Binders & Liquids:
- 2 Large Eggs, at room temperature – Helps bind and provides richness.
- ½ cup (120ml) Milk (Dairy or Unsweetened Non-Dairy like Almond, Soy, or Oat Milk), at room temperature.
- ½ cup (120ml) Vegetable Oil (Canola, melted Coconut Oil, or other neutral oil) OR Melted Butter (dairy or non-dairy) – Provides moisture and tenderness. Applesauce can replace some oil for lower fat, but may alter texture.
- Leavening & Flavor:
- 1 teaspoon Baking Soda
- ½ teaspoon Baking Powder
- ½ teaspoon Salt – Enhances all flavors, especially chocolate.
- 1 teaspoon Pure Vanilla Extract
- Optional: ½ teaspoon Espresso Powder – Dissolved in vanilla or milk, enhances chocolate flavor without tasting like coffee.
- Optional: ½ teaspoon Ground Cinnamon – Complements chocolate and zucchini subtly.
- Optional Add-ins:
- ½ cup Chopped Walnuts or Pecans
Ingredient Notes & Considerations:
- Gluten-Free Flour: The success of GF baking often hinges on the flour blend. Using a reputable “cup-for-cup” or “1-to-1” blend containing xanthan gum is highly recommended for ease and reliable results. If your blend doesn’t contain xanthan gum, you’ll likely need to add ½ to 1 teaspoon separately. Different blends can absorb liquids differently, so slight variations in batter consistency are possible.
- Zucchini Prep: Do not skip squeezing the zucchini! Shred it finely (using the small holes on a box grater). Place shreds in a clean kitchen towel or several layers of paper towels and wring out as much water as possible over the sink. Excess water will make the muffins dense and gummy. Measure after squeezing.
- Cocoa Powder: Dutch-process cocoa powder is alkalized, resulting in a smoother, darker, more intense chocolate flavor that works beautifully here. Natural cocoa powder is more acidic and will yield a slightly lighter color and sharper flavor.
- Room Temperature Ingredients: Using room temperature eggs and milk helps the batter emulsify properly, leading to a more even texture and rise.
- Chocolate Chips: Using a mix of mini and regular chips provides great chocolate distribution. Adjust the amount based on your preference. Ensure chips are certified gluten-free if Celiac disease is a concern.
Instructions
- Preheat and Prepare: Preheat your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners or grease it well.
- Prepare the Zucchini: Wash the zucchini and trim the ends. Shred it using the fine side of a box grater (no need to peel). Place the shredded zucchini in the center of a clean kitchen towel or multiple layers of strong paper towels. Gather the ends and twist tightly over the sink, squeezing firmly to remove as much excess water as possible. You should get a significant amount of liquid out. Set the squeezed zucchini aside. Measure out 1 ½ cups after squeezing. This step is critical for texture.
- Whisk Dry Ingredients: In a large bowl, whisk together the gluten-free flour blend, cocoa powder, sugar (if using granulated), baking soda, baking powder, salt, and optional cinnamon or espresso powder. Whisk thoroughly to combine and break up any lumps (sifting the cocoa powder and flour blend is recommended for the best texture).
- Combine Wet Ingredients: In a separate medium bowl, whisk together the room temperature eggs until lightly beaten. Whisk in the milk, oil (or melted butter), and vanilla extract until well combined. (If using brown sugar or coconut sugar instead of granulated, whisk it into the wet ingredients until dissolved).
- Combine Wet and Dry: Pour the wet ingredients into the bowl with the dry ingredients. Mix with a rubber spatula or wooden spoon just until combined. Be careful not to overmix. Some small lumps are okay. Overmixing gluten-free batter can lead to tough or gummy muffins.
- Fold in Zucchini and Chocolate: Gently fold the squeezed, shredded zucchini into the batter until evenly distributed. Reserve about ¼ cup of the chocolate chips for topping. Fold the remaining ¾ cup of chocolate chips (and optional nuts, if using) into the batter. Again, mix gently and minimally.
- Fill Muffin Cups: Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds to three-quarters full. A large cookie scoop (about ¼ cup size) works well for portioning evenly.
- Top and Bake: Sprinkle the reserved ¼ cup of chocolate chips evenly over the tops of the muffins in the tin.
- Bake: Place the muffin tin in the preheated oven. Bake for 18-24 minutes, or until a wooden toothpick inserted into the center of a muffin comes out clean or with moist crumbs attached (melted chocolate doesn’t count). Cooking time can vary slightly depending on your oven and GF flour blend.
- Cool: Let the muffins cool in the muffin tin on a wire rack for 5-10 minutes. This allows them to set slightly. Then, carefully remove the muffins from the tin and place them directly on the wire rack to cool completely. Cooling fully on the rack prevents steam from building up and making the bottoms soggy.
